my little 5 year old step sister got sick at 11pm. i wasnt sharing anything with her or eating around her at all today. they were out at a restaurant but i stayed home and rode bike all day. so i had very little contact. i did touch a phone she touch early in the day with my hand but i used hand sanitizer when i got home and ate. i lysoled my room, and i have my own bathroom. if i just stay in my room and not eat will i be fine?

i am so paranoid, i can't sleep at all. its 3am
